Direct any of your video output to different locations for display, recording, broadcasting — you name it!
» 4 x 4 video switch.
» Enough bandwidth to handle 1600 x 1280
resolution at 85 Hz.
» Just press a button to switch any input
to any output.
» Has universal power supply—can be used
almost anywhere.
» Designed for VGA, but can support almost
any kind of video with the right cabling.
» Can drive video as far as 150 ft. (45.7 m).
» Front-panel LEDs make it easy to figure out
where video is going.
FEATURES
If you have several sources of video that you’d like to display at
different places at different times, here are a few things not to do:
1. Don’t settle for static, expensive dedicated video feeds.
2. Don’t swap video cables by hand.
3. Don’t subject your video devices to ugly and potentially
damaging mechanical video switching.
4. Don’t pay for extra switching (keyboard, mouse, etc.)
that you don’t need.
What should you do? Consider ServSwitch
™
Brand Matrix Video
Switches. You can use them to electronically switch video signals
from four source devices among video screens.
In the standard application, computer CPUs will be the sources
and computer monitors will be the destinations. But with the proper
cabling and signal conversion (and as long as the destination devices
can handle it), almost any video device can be involved—TVs, VCRs,
cameras, projectors, DVD players, etc.
This is because the switches can handle almost any kind of
video synchronization: RGBHV (as used in VGA, SVGA, and other
types of computer video), RGBS (as used in NTSC and PAL TV
signals), and RGsB (“sync on green”). They have a vast amount of
bandwidth—enough to carry video at resolutions up to 1600 x 1280
at refresh rates up to 85 Hz. All inputs and outputs are buffered,
so you always get the sharpest possible images.
The 4 x 4 switch can drive signals up to 150 ft. (45.7 m).

ServSwitch Brand Matrix Video Switches can be controlled in either
of two ways. For one, it can be controlled with a standard serial
numeric keypad, powered by the Switch, that plugs into the Switch’s
rear panel. Press the keypad buttons in the sequence output–decimal
point–input–Enter key to make a switch. For example, press [3][.][1]
[Enter] to switch the input from CPU #1 to output to monitor #3.
If you press zero for the input number, the output channel will be
blanked (the Switch won’t send it any video signal). If you press the
asterisk key for the output number, the input channel will be broadcast
to all outputs. LEDs show you which output channel is receiving which
input.
The keypad’s cable is 6 ft. (1.8 m) long, but you can use DB9
extension cable (not included) to extend your “roaming radius”
to RS-232’s maximum distance of 50 ft. (15 m). The switch includes
one keypad.
The other way to control a switch is by attaching a PC or other
serial device that can send the Switch the ASCII characters or hex
codes equivalent to the keypad keypresses. In this way, switching
can be automatically controlled for displays, demos, and so on.
Each switch has a universal power supply; with the proper input
cord, you can plug it in just about anywhere in the world.

Call us about UPSes and AC-power surge protection; we’ll help you
determine the best equipment for your application.
CAUTION: If you use adapters or converters to attach non-VGA
equipment, all destination devices must be capable of handling the video
signals from all source devices. For example, driving high-end workstation
video to a monitor whose maximum refresh rate is too low could result in
oversyncing and damaging the monitor.
